: DC current for an approximate temperature rise of 40°C without core
loss. Derating is necessary for AC currents. PCB layout, trace thickness and
width, air-flow, and proximity of other heat generating components will affect
the temperature rise. It is recommended that the temperature of the part
not exceed 125°C under worst case operating conditions verified in the end
application.

5. Part Number Definition: MPI5451Rx-yyy-R
- MPI5451Rx = Product code and size
- yyy= Inductance value in uH, R = decimal point, if no R is present then third
character = number of zeros
- “-R” suffix = RoHS compliant
